Abstract: The present invention relates to advanced Cherenkov-based imaging systems, tools, and methods of feedback control, temporal control sequence image capture, and quantification in high resolution dose images. In particular, the present invention provides a system and method for simple, accurate, quick, robust, real-time, water-equivalent characterization of beams from LINACs and other systems producing external-therapy radiation for purposes including optimization, commissioning, routine quality auditing, R&D, and manufacture. The present invention also provides a system and method for rapid and economic characterization of complex radiation treatment plans prior to patient exposure. Further, the present invention also provides a system and method of economically detecting Cherenkov radiation emitted by tissue and other media in real-world clinical settings (e.g., settings illuminated by visible light).

Abstract: A Cherenkov-based or thin-sheet scintillator-based imaging system uses a radio-optical triggering unit (RTU) that detects scattered radiation in a fast-response scintillator to detect pulses of radiation to permit capture of Cherenkov-light or scintillator-light images during pulses of radiation and background images at times when pulses of radiation are not present without need for electrical interface to the accelerator that provides the pulses of radiation. The Cherenkov images are corrected by background subtraction and used for purposes including optimization of treatment, commissioning, routine quality auditing, R&D, and manufacture. The radio-optical triggering unit employs high-speed, highly sensitive radio-optical sensing to generate a digital timing signal which is synchronous with the treatment beam for use in triggering Cherenkov light or scintillator light imaging.
